I have an 87 IROC and it doesn't have a serp belt system on it. I can't seem to find a SC kit for it.

Also I have a 355 w/ 10:1 flat tops, a .554/.554 hyd roller cam, and a HSR w/ 38# injectors and 58mm TB. I haven't got a set of heads yet. Is this setup going to work with a SC ?

You can get paxton ones for v belt but those chargers suck imo.

Are you still running A/C? If not, ProCharger has a carb Chevy bracket that would bring the blower in closer to the motor. You'd have to use some universal brackets to relocate the alt. to the pass. side, and ProCharger has a bracket that locates a Jayco style P/S pump down low out of the way. Plus the crank pulley they would have you use with the carb Chevy bracket wouldn't stick out as far, putting less load on the crank snout.
